Earlier problem was GHD to KTES was unelectrified Single line section with sectional capacity crossing 130 to 150% .

Things are changing and this section will surely be utilized for running express and superfast trains movement as from states it will be short or marginally long for the places

I hope you are unaware of industries and cities that this route passes through, Renukut, Bargawan, Singrauli, Anpara, Shaktinagar. I am unaware of what economic activities you are seeking for as both places generate revenue for state government that is only after Noida then Sonbhadra in UP and Indore then Singrauli in Madhya Pradesh

There is huge demand for new trains but railways has other priorities to ferry coal and fulfil the needs of large masses. Here people are in vicinity of DDU, BSB, and hence are dependent on those cities as UPSRTC buses are available in every 30 min henceforth people are managing.

Yes true there's no new train except RNC Rajdhani diversion via Chopan, but freight traffic is still very high that's around 50-70 trains daily.

Also to conclude there are sections in all trunk routes which are sparsely populated but that doesn't means trains aren't passing through them. You can take example of following sections

Itarsi to Nagpur no big settlements in 300 km ( Except Betul that's also NS4- station ),

Prayagraj to Kanpur no big settlements in 200 km ( Except Fatehpur that's also NS4- station ),

Moradabad to Saharanpur no big settlements in 200 km ( Except Nazibabad that's also NS4- station )

Kharda road to Vizianagaram Jn Except Brehampur no big settlements that's NSG-3 station.

Similarly Itarsi to Khandwa, Itarsi to Jabalpur ( 180 and 200 km)

but still train are plying non-stop Imagine it as train departed from DHN then next halts till Katni can be DHN ( NSG-2), CRP ( NSG- 3), BRKA ( NSG-4) , DTO ( NSG 3), GHD (NSG- 4), RNQ (NSG 4 from this year), CPU ( NSG 5 from this year) , SGRL ( NSG 4) , KTE ( NSG-3 ). Source /blog/post/5716888

DHN BRKA 120 Km ( Can bypass BRKA with PTRU or RRME halt

BRKA to DTO/GHD ~ 200 km

GHD/ DTO to RNQ ~ 120 km

RNQ to SGRL - 100 Km ( CPU bypassed )

SGRL to KTES 250 Km

As we don't have much trains here hence revenue from passenger train movement is very low. As if train are start to run then CREW can be changed at GHD and SGRL, also distances are justified for halts for long distance trains and these places have potential to fill train of any kind as they will be intermediate stations with RL Quota.

It's about intension of railways, they have over emphasized on DDU PRYJ section for passenger trains traffic and pushed freights via CIC as these are already coal loading points. Hence huge flow of traffic so currently no room for new trains even now despite being fully electrified and 3/4th doubled.
